Rolled Annealed and Electrodeposited Copper Foil Copper foil is made by two processes, and the foil that results is different in ways that matter to a flexible circuit and hardly at all to a rigid one. The difference is in the grain structure, and it shows up as ductility rather…

Panel Rail Design Rules The panel rail is the part of the panel that the machine holds, and it is often designed last, after the boards have been placed. That order of work is the reason so many panels handle badly: rails that are too narrow to support the panel,…

Solder Bridging Control on Fine Pitch Assemblies A solder bridge is a connection between two joints that should be separate. On a fine pitch assembly the joints are close together, the paste volume is small and the margin between a good joint and a bridge is narrow, so bridging is…

PCB Conveyor Handover: Design and Assembly Considerations Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB conveyor handover from the perspective of a PCBA factory floor, covering handing…

PCB Placement Nozzle Standards: Design and Assembly Considerations Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB placement nozzle standards from the perspective of a PCBA factory floor,…

PCB Conveyor Specification: A Practical Review for Manufacturing Teams Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article…

Cleaning After Hand Soldering Hand soldering leaves more residue than any machine process, because the operator applies flux locally, often more than the joint needs, and the heat source is a tip rather than a controlled profile. Some of that residue is harmless and some of it is not, and…

PCB Placement Nozzle Problems: A Factory-Floor Review Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB placement nozzle problems from the perspective of a PCBA factory floor, covering…

PCB Placement Nozzle Training: From Design to Repeatable Production Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB placement nozzle training from the perspective of a PCBA factory…

PCB Placement Nozzle Cost: From Design to Repeatable Production Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB placement nozzle cost gives you a practical advantage…
